Fungitell, CSF
Use
The Fungitell Beta-D Glucan assay is indicated for the presumptive diagnosis of invasive fungal disease by detecting elevated levels of (1,3)-Beta-D-glucan in CSF. This beta-glucan is sloughed off from the cell walls of various pathogenic fungi, and elevated levels in CSF can serve as a surrogate marker for invasive fungal infections. The assay detects Beta-D-glucan from pathogens like Candida, Aspergillus, and Coccidioides, providing crucial data for diagnosing and managing fungal meningitis and other invasive fungal diseases.
Special Instructions
Not provided.
Limitations
The Fungitell assay does not detect certain fungal species, such as the genus Cryptococcus, Zygomycetes (like Mucor and Rhizopus), and it has limited detection capability for Blastomyces dermatitidis due to low levels of beta-glucan production in these fungi. Furthermore, there are no established criteria for interpreting results from CSF, and the performance characteristics in CSF have been evaluated by Eurofins Viracor. Reference ranges are not available for CSF.
